Responding to a Tribune story about whether an alleged sex crime by a Stagg High School student was reported to authorities, Principal Eric Olsen has left a message at students' homes and on the school's website assuring parents the school is safe.

"I hope that as you read about the allegation referenced in this article you consider the services that Stagg High School has provided to your students and know that we hold the safety and security of all Stagg High School students as our chief concern to ensure an environment that supports learning at high levels for all," Olsen said in the message.

The message is not signed by Olsen nor does it include Olsen's name. But Carla Erdey, communications director for Consolidated High School District 230, which includes Stagg in Palos Hills, said the message is from Olsen.

The Tribune reported on Saturday that southwest suburban police are investigating if a developmentally disabled student's allegation of sexual abuse by another student at Stagg was not reported by a school staffer to police as required by law, according to a source familiar with the probe.

Officials from several police departments met with a Cook County prosecutor last week to express concerns about the lack of reporting. Dan Kirk, chief of staff for State's Attorney Anita Alvarez, confirmed the meeting took place at the Bridgeview Courthouse and included representatives from police departments in Palos Hills, Palos Heights, Palos Park and Hickory Hills -- all towns that feed students to the school.

A source said police also are looking into whether there were more Stagg students who were sexually abused. Kirk declined to say how many alleged incidents there might be, but he said they happened within the past several weeks.

But Olsen said in his message that Stagg High School is not aware of any alleged acts of sexual abuse at the school in the past several weeks.

"In fact, we have not been made aware of any allegations of sexual abuse that may have taken place this school year," Olsen said. "Any past allegations of sexual abuse, as well as any inappropriate behaviors by students that have been brought to the attention of staff at Stagg, have been addressed and consequences fully applied with the involvement of the police and outside agencies as necessary."

Olsen did not return phone or email messages last week.
